The pressure will increase if the gas is changed from nitrogen to helium.
Kinetic theory of gases
The question is incomplete but I will try to help the much I can. We must note that the kinetic energy of the molecules of a gas depends on the temperature and the molar mass of the gas.
Since the average velocity of a gas depends on molar mass also, the pressure will increase if the gas is changed from nitrogen to helium.
